(Automotive) So you're gradually losing coolant from week to week and you don't know why? If you're like me you're discovering new things about your car every week(studying automotive technician and diyer). So you try to diagnose what the problem is. I tested the radiator and cap pressure(though I didn't check both seals of the radiator cap) in school. So I knew I couldn't be losing coolant there. And since I didn't check the other cap seal, I replaced the cap anyway. I also checked the water pump vanes because if coolant is leaking from the pump seal, it would show on the vanes. I got nothing. I suspected a blown head gasket, but the only symptom I could come up with was the loss of coolant. No excessive white smoke coming out of the exhaust, and no coolant smell in the exhaust smoke. No external leaks and no noticeable smell of coolant somewhere in the system.My first thought was ok now I'm screwed. It's either a hole in my cylinder or block. Or it could have been the freeze plugs,...

(Automotive) Bottom Line: This stuff works incredibly. I tried 3 other well-known stop leak products, two different Prestone's and K-Seal and they failed. I had a head gasket leak in my 1995 Mitsubishi 3000GT, mint condition, but moderate coolant leak. All other coolant system components were almost new: radiator, radiator cap, upper and lower hoses and water pump. 1 Jug of coolant still leaked about every 3 weeks and made for a mess and strong toxic odor. Liquid Copper worked incredibly. The Liquid Aluminum may also work (I didnt try), but I would stick with the liquid copper as fixing any coolant leak you have. Poured it directly into the radiator which was about 80% full, drove 10 miles, topped off radiator 100%, and within 100 miles the leak was completely sealed, no leaking on ground, or in/around engine bay. Saved me well over $1,000.00. Thank you very much to Bar's for their superior products, and for saving my coolant system and vehicle from major costly repairs. 1 of 1 people found the following review helpful Fixed my Dodge Cummins diesel block, Amazon Verified Purchase This review is from: Bar's Leaks 1109 Block Seal Liquid Copper Intake and Radiator Stop Leak - 18 oz. (Automotive) I found out I was loosing coolant as I had the dreaded "53" Cummins engine block in my 2001 Ram. I tried this because the options are few - replacement short block is $5000 or a $1000 drill and mash in block filler metal. To my very happy surprise the Bar's Leaks 1109 worked great and all I had to do was pour it in the rad leaving the antifreeze in there. Just make sure you remove enough coolant from the radiator to fit the whole bottle in the rad. DO NOT put any in the oveflow bottle as it will plug the siphon tube and you'll have to clean the canister out. |
